DOVERS new Optidrive Plus range delivers its full rated torque at zero speed, without overheating the motor or needing any form of feedback device.
To perform this feat, the drive measures voltage and current very precisely and performs continuous real-time tuning of the motor parameters.
The Optidrive Plus is not designed to hold the full torque at zero speed indefinitely. In typical applications, 10-20 minutes should be the maximum.
Other characteristics of the new drive include: eight preset speeds; built-in PI control; continuous real-time tuning of motor parameters; simple set-up using the motor's nameplate data; and programmable S-ramps.
